WOW!!! But not as "exciting" and I thought it would be... Maybe one of those things better seen live? Makes me think they used some sort of Magnetic device to keep it tight to the track over the top? (that's my conspiracy theorist coming out!)... Still impressive!

I just watched this on TV, a little bit of a recap. This is really amazing. I don't think they used any magnets to help, honestly I think it is just straight physics. They went into a little bit about what is needed to accomplish the feat. The cars had to be between 48-52 mph when entering the loop...too slow and they fall off the loop, too fast and the front bumper will hit the beginning of the loop, friction, control, all bad. They hit 7Gs going through the loop, have to keep their head back, eyes open and try to maintain control. Cars were raised for the event, with very stiff suspension and special tires. Tires had to be 80psi. When the feat was achieved, the second guy almost missed the landing after the jump, very close.
